The box or casing 1 containing the belts and parts associated therewithis substantially rectangular and is preferably formed from sheet. metaland has both the front and rear sidesthereof closed by rectangularframes 3 and 4.- fastened thereto by screws 5 and containing transparentplates 6 and 7 such as of,

13 and the bearing sleeves 14: of the brackets 10 and 12 are verticallyaligned as are those bearings 14 of the brackets 11 and 13. Centrally tothe rear of the box, we permanently'secure also similar upper and lowerbearing brackets 16 and 17 which have their inner ends forked to providereceiving bearings 18, the upper bearing 18 being axially w three a PM au i. are

aligned with the upper bearing sleeves 15 and the lower bearing 18 beingaxially aligned with the lower bearing sleeves 15.

It will be apparent that we have six bearand such bearings are utilizedto rotatab y siiii and lower pairs of shafts 19-and ,the inner ends ofthe shafts "being carried w w bearings 15. The outer endsof the an allreduced as indicated at 21 to enter the bearingsla and the inner ends ofthe shafts are retained within the bearings 18 by cotter pins 22. On theshafts, we mount rotatably upper and lower pairs of rollers 23 and 24,'these "rollers being formed'from opppsing end heads 25 an 26 connectedtogetherfby atube or pi 2 of predetermined l The pairs o'f i'ollerscarry belts 28 an 29. I

In pr der 'to. fasten the ends of the belts to marc er or windin drumsin a simple and efl'hctive'manner, we ave provided the ends of the beltswith hems 30 and have passed a retaining rod 31 into each hem. The tubes27 y are longitudjnall slotted as indicated at 32 to'peimit the end ofthe belts to pass therethrough but the width of the slot in eachinstance is less than the diameter of the rod so that the rod cannotpull out tlllfOlV'll the slot. u In order to enter the rods, we holes 33in the inner heads of the winding drums. When the belts are to befastened to the drums, the hemmed ends thereof are passed through theslots and brought into '3q a position aligned with the holes33. One

then asses the rods through the holes and into t e'hem, the rod beingpushed in until it is free of the head at which time, it will drp d Wuand serve as an anchor retaining au the] efil from withdrawing throughthe slot. To 1 e outer heads of the drums, we secure by screws bevelpinions 34 and these pinions of the'upper and lower drums are contnuousl in mesh with upper and lower 45 bevelgears 35 and 36 mounted onsimilar vertical'ly disposed winding shafts 37 and38. Each ofthe lattershafts has its upper end contracted to ,provido a shoulder 39 and aspindle 40 thereabove, the spindle 40 being rotatably received in the upper boa ring sleeves 14 and also carrying rotatably the upper gear@wheel 35 which is supported b the shoulder 39. A cross pin 41 passesthrough the upper end of the spindle and a wearing up er end of theupper sleeve 14. t 1s holding t shaft a roast we we I a x are nclo edwithin pipes or tubes 43 and swlgnpe f lpgmg their ppe ends screw ree,pm, $5 45 fast ed-t0 the 1. a 5! a Q 5 p a e 9. and hen lo er ends gdorecelvea bearing lee've 4,6.

Ajam screw 5O fastens the head ltifi crank to the shaft.

e under face of the bearing sleeve is provided-with a plurality ofequi-spaced semicircular poekets 51 and there isprofembiy an dd numberof th s p c e T e uppe f e of the head 47 is drill d to provide two d1-ametrically opposite pockets 52 and 53 which .nceirzesprings 54 andcatches 55 in the form of balls. The upper ends of the drilled pockets52 and 53 are struck in to prevent the balls from escaping from thepockets but it will here be observed that there is suflicient of theball permitted to protrude from the pocket funde'rthe ressure of thespring to form a depressib e catch engageable wi h one or other of thepockets 51.

By having the balls 55 diametrically opposite and an odd number ofpockets 51, we obtain a relatively line adhstment of the head 47inregard to the sleeve 46, as one ball will enter one of the pockets topreventundesired rotation of the head 47 and the h rbe l w ll be idingth lac of he sle ve 46' between the pockets thereof. Obviously thetui'ningipf the crank i mitrols the rotat on of the'shaft 37 or 38 asthe case may he and the shaft will be i'eleasably locked in anydefllGCLpositimr by theentrance of one or otherof the ballsin one orother of the pockets 51.

The gear wheels 3.6 liereinbefore mentioned are both perinanentlfastened by pins 56 to the shafts 37 an 38 so that the lower w ndingdrums are: ositiyely driven by the sh afts. The upper evelgears 35,however, are rotatably mounted on the spindles of the shafts and theonly driving connection b tween the shafts and the upper bevel gears isby way of. coiled springs and 58 mounted on the shafts and having theirlo er ends permanently fastened at 59 to the Shafts and their upper endspermanently fastened at 60 to the upper bevel gears 35.

These springs turn the bevel gears 35when the shafts are turned andserve to compensate for the gradual variation in the d gn eters of thewinding and unwinding ends of the belts as will be re dily understood,-

The belts are Pr v ded throu heat than length with the numbers 012345689 a aping in arithmetical progression thro qiul th h a th 8f the has,the-auruber% placed thereon in any suitable manner. 3 11nd a: desirab tohav the belts mad rom a l k flexi e a d W p r g thereon an whi e so thatthe. is a siiarp contrast. The belts are made p c-M y ia v ples t0 heglass; wind w '7' through which the numbers thereon he clearly a and inthis osmium m might point out that when the device is in use, only onenumber on each belt should be seen at one time. In Figure 1, we haveshown in dotted outline the numbers 38 as appean ing through the window7 and these numbers indicate the route number 38.

The inner edges of the belts are guarded by a vertical strip 61 whichcan be also painted black and this strip carries a centrally locatedvertically disposed plate 62 which extends vertically between thebearings 18 and is utilized to carry similar pointed indicators 63 and64. The indicators are both fastened by a bolt 65 to the plate, the boltpassing through a suitable hole provided in the plate and elongatedslots 66 in the bases of the indicators. This arrangement allows eitherof the indicators to be adjusted vertically in respect to the adjacentbelt. The belts are both provided at their inner edges and on their rearfaces with stopmarks 67 selectively positioned in respect to theadjacent belt numbers. e have considered it desirable to use smallnumbers on the belts as stop numbers, the small number corresponding ineach instance to' the adjoining large number.

7 In orderthat the motorman or other operator may be able to properlyset the annunciator without leaving the car vestibule, we have provideda transparent peep opening 68 in the roof of the car throughwhich themotorman can see the indicating pointers and the stop marks andobviously if he wants to set the belts to indicate the route number 38,

he will turn the respective belts until he sees the small stop numbers38 positioned opposite the pointers at which timevhe knows that theroute number is properly positioned in respect to the window 7.

In placing this device on say the front end of a street car vestibule, asubstantiallv rectangular hole 69 is cut in the roof of the vestibuleand this hole permits the box to be passed upwardly therethrough untilthe projecting ends of the plate 8 strike the under side of the roof.The roof carries bolts 7 0 and 71 which are adapted to pass into thebolt openings 9 of the plate and the whole device is held in place bywinged nuts 73'screwed up against the ends of the plate. Thisarrangement makes it very convenient not only to put the device in placebut also to dis mount it'from the car at any time. The cranks 48 and 49vare located within convenient range of the motorman and the wholearrangement is such that he does not require to leave his usual positionin the vestibule in order to see and set the belts.

The glass plates 6 and 7 forming the windows are'held between resilientstrips 74 and 7 5 so that there will be no rattling and such thatthejinterior of the casing Wlll be dust aroof and weather proof.
